JAMES M. HUNTER, OF ST. LOUIS, MISSOURI, ASSIGNOB TO THE AMERICANBOLSTER SPRING COMPANY, OF SAME PLACE.

BOLSTER-SPRING FOR WAGONS.

SPECIFICATION forming part of Letters Patent No. 380,574, dated April 3,1888.

Application filed January 10, 1888. Serial No. 260,346. (No model.)

To all whom it may concern.-

Be it known that 1, JAMES M. HUNTER, of the city of St. Louis, in theState of Missouri, have invented a certain new and useful Improvement inBolster-Springs, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification, and in which- Figure I is a perspective viewof the upper and lower portions of the box with the springs andconnecting-bolts removed. Fig. II is part in side view and part invertical section with the springs and bolts in place. Fig'III is a topview with a standard in section taken on line III III, Fig. II. Fig. IVis a vertical longitudinal section taken on line IV IV, Fig. Ill.

My invention relates to an improvement in bolster-springs for wagons,andrelates particularly to an improvement on Letters Patent granted toWesley Cole, December 25, 1883, No. 290,860.

My invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claims.

Referring to the drawings, 1 represents the lower member of a box,whichconsists of pockets 2 to receive the lower ends of the springs 11,and aweb, 3, connecting the pockets. This member is placed over the bolster 4of the wagon, (see Fig. 11,) one pocket fitting on each side of thebolster and the web 3 resting on top of the bolster.

5 represents ribs or flanges on the pockets, which bear against thebolster and prevent the lower ends of the pockets from bending inward,as they would be liable to do in the absence of these ribs.

7 represents strengthening-flanges on the sides of the connecting-web 3.

8 represents perforated lugs extending outward from the top of eachpocket.

9 represents the upper member of the box,

which is provided with sockets 10 to receive the upper ends of thesprings 11, the lower ends of whiohfit in the pockets 2, as stated. Thismember is provided with a recess, 12, to receive the board 13 of thewagon-bed, as shown in Figs. II and 1V, and it is also provided withperforated lugs 13 and brackets or projections 14, the latter straddlingor embracing the standard 15 of the bolster, as shown in Figs. III andIV.

16 represents connecting bolts passing through the perforated lugs 8 and13, and which serve to connect the two members of the box, but which donot prevent the parts from moving to and from each other as the springscompress and expand. These bolts 16 have heads on their upper ends, asshown in Fig. III, and pins 17 are passed through their lower ends.

I claim as my invention 1. In a bolster-spring, the combination of a boxcomposed of an upper and a lower member, and springs located between themembers, the lower member consisting of two pockets united by a web andhaving flanges 5, substantially as and for the purpose set forth.

2. In a bolster-spring, the combination of the box composed of twomembers and springs located between the members, the lower memberconsisting of pockets connected by a web having strengthening-flanges 7,substantially as and for the purpose set forth.

3. In a bolster-spring, the combination of the springs and box composedof two members, the upper member having projections 14, sockets 10, andperforated lugs 13, and the lower member having perforated lugs 8 andbolts passing through the perforated lugs, substantially as and for thepurpose set forth.
